To make your aquarium look even more natural, you can use decorative elements. Think of a piece of wood, a root of a shell. Decorative elements can also be made from ceramics. For a natural touch in your aquarium you can choose natural material or ceramics that look natural, for example in the shape of a branch.
Aquascapers often use plants and moss on decorative elements. They fix them with glue or a thin tread. A perfect eyecatcher!
